MOTOR-METER LOCK'.

Apniicanon me?! August 27, 1923. serial N0. 659,467.

To ad fui/ulm, it may con-cern:

le'it known that I', Fnnn Dn (lAnnY, a ritizenvof the United States,and uy resident yof Chicago, in the county of (look and l@tate of lllinois, have invented certain new and useful improvements in a Motor-Meter Lock, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same. v

My present invention relates to improvements in radiatorcaps for automobiles and particularly to radiator caps of a decorative design and in which maybe installed a motormeter or other device for indicating the temperature of the water in the radiator. A highly desirable, i'tnot necessary, feature oi' such devices is that they should he so constructed that when attached to the radiator it will be very difficult or impossible to remove them and thereby prevent the theft of the cap and the motormeter or other temperature 'indieatinfr device mounted thereon. It has theretore been one of the objects of my present invention to provide a radiator cap which may he readily installed, but which,` after installation, will be extremely diflieult or impossible oi' removal. .Other objects of my invention are to providel a neat and attractive radiator cap which can be manufactured and .sold at an economical figure.

1 .prefer to attain the for-agonier objects by means of the structure illustrated in the in whieh,`

Figure 1 is a. front or forward elevation of a radiator cap embodying my vinveition; and mounted upon a radiator spout.

Figure 2 is a central transverse section of the structure shown in Fig. 1 with a frag-I .ment of the upper frame of a motormeter assembled therewith;

Figure 3 is an elevation ment of the cap;

vFigure 4 is an elevation of the intermediate element of the cap which makes serew-threaded assembly with the spout of a radiator;

Figure 5 is a top plan of the Structure shown in Fig. 4; i

Figure 6 1s a section of a modified form of the structure Shown in Fig;u 4 for assembly with an exteriorly threaded radiator spout;and K Figure 7 is a plan ofthe split ring for of the inner ele;

retaining the moiormeter coimeetioneo'ver in place.

Figure 8 is a. tragmental plan.

The cap comprises an exterior preferably cylindrical easing, 8, provided upon one side with parallel upwardly extending ears or l'iraekels. 9, between which is spivoted a plate, 10. extending from a closure or cover. '11. This closure or cover is provided with a, forwardly extending embossment, 12, over which engages a Wire loop or bale, 13, the

ends of which are pivoted in oppositely,

bored enibossn'ients, 14 provided upon the forward portion of the easing, 8.

For decorative purposes I have provided ball headed arms, 15, extendingr from each side of the casing, 8.

The casing, 8, is of a size to rest upon the top of the radiator spoilt, X, with which it is to be assembled, and the lower portion of the bore of the easing` 8, is reduced to provide a shoulder, 16, The casing, 8, is secured to the radiator spout by means of the intermediate element, 17, which is an annulus, the lower end of which is exteriorly threadi-fgl to screw into the end of the radiator spout, and from the upper edge of which extends a rib or flange, 18, to engage the shoulder 1G of the casing 8.

The structure. as so far described, will permit the turningf of ihe outer casing without turning the intermediate element or anianlus. 1'4", and therel'iy detaohing the cap from the radiator spout, but if a. pair of pliers 'which will engage both the easing and annulns are1 employed; these members may be detached "from the radiator. rlo prevent Such a eontinge. ,ey have sot into the top face ofI the a-nnnius a apri ng ratchet do or detent,'1 and have provided an additional annnlus, A), having a lateral flange,- 21, ai? its upper edge which extends over and coversY the top ot' the intermediate element, 17, and which is long enough to exl"tend to the bottom of said intermediate elenient and prevent access thereto.- The under edge of the flange 2l is eut back to provide a shoulder, 22, for engaging the dog-or detent 19, and a screw S is inserted through nulus engages with the dog or detent- 19 on the intermediate annulus 17 so that the lat-- ter is rotated with the structure and is rection will not disturb the annulus 17 because the shoulder 22 will be disengaged from the dog or detent, and said annulus cannot be vunscrewed from the spout, and consequently the cap cannot be removed. Upon completing the mounting or assembling operation the screw S may be removed and theI arms 15 and casing 8 may be rotated jin either direction.

In Fig. 6 I have shown the intermediate annulus, 17, interiorly, instead of exteriorly, threaded, but, it is obvious this makes no difference in the manner of. operation of my device.

A packing Washer, 23, is preferably laced upon the top of the inner element fore the cover is closed. Also it should be noted that the cover is so proportioned that the inner element must be inserted in the casing 8 before the cover is assembled and cannot be taken out until the cover is disassembled from the casing. As the cover pintle does not extend entirely through one of the ears 9 this is a ditlicult job requiring the requisite tools, skill and time, and is not a job which would be attemptedby an unauthorized person upon the street or in a public place.

In connection with the motorrneter which is installed in the cover I have provided the centrally perforated washer, 2 4, the edge, 25 of which is slightly dished, and I have provided the interior of thc closune or cover,

1. A radiator-closure comprising an ani nulus having a lateral shoulder thereon, a centrally perforated cap hingedly secured to said having a flange engaging with the shoulder of said annulus, an interior element covering `the juncture of said before-mentloned an-l nulus and saidunion element, a pawl 4and annulus, a threaded union` element ratchet oo-actively relating said union and Y.

covering elements, and means for preventing the Withdrawal of said covering element.

2. A radiator closure comprisin an in-l teriorly shouldered sleeve, a cap ingedly mounted thereon, an exteriorly shouldered tube rotatablymounte'd in said sleeve 'and threaded for-screw engagement with'` a 'rai diator spout,r a third member'upon the interior of said' tube,

and means interposed between said tube and thirdA member. for

securing combined in one direction.
